YH1.5W-0.22~0.66KV lightning surge arrester

The electrical equipment used by the Zinc Oxide lightning arrester to protect the AC power system is protected from overvoltage and overvoltage damage.

Purpose

The Zinc Oxide lightning arrester is the most advanced over-voltage protector in the world. Because its core component resistors are made of Zinc Oxide and various metal oxides, compared with traditional silicon carbide arresters, it greatly improves the volt ampere characteristics of resistors, improves the capacity of resistors, and brings about the fundamental change of the characteristics of arresters.

When the lightning arrester under normal operating voltage, the current flow through the arrester only microamp level when subjected to voltage, non linear volt ampere characteristics of arrester excellent function, current flow through the arrester moment increased to several thousand amperes, lightning arrester in the conducting state, the release of piezoelectric energy, so as to effectively limit over against the voltage of power transmission equipment.

Use Condition

The temperature of the environment is not higher than +40 ℃, not less than -40 ℃.
The altitude is not more than 1000 (the plateau should be marked at the time of order).
The frequency of the power supply is not less than 48Hz, not more than 60Hz.
The power frequency voltage applied to the arrester for a long time does not exceed the continuous operating voltage of the arrester.
Maximum wind speed is not more than 35m/s;
The earthquake intensity is 7 degrees and below.
Mark the stain area.

Technical Performance

The performance of the products can meet the requirements of GB 11032-2000, JB/T8952-2005, JB/T10497-2005 and DL/T815-2002.
